Figure 24 is the action specification figure of the example done of the software upgrading merit of explanation base station.Net management device (250) is at first carried out (groupization) that the base station of update software is selected with predetermined rule and is handled (24-1).In the following processing (24-1), the set of the base station of selection is called group of base stations 1 (800-1).The selection of base station can adopt the method shown in for example above-mentioned Fig. 7～Figure 12 and the explanation thereof to realize.In addition, call out linking number by each sector and each frequency management, the calling linking number of base station can adopt these aggregate value.
Net management device (250) passes on to group of base stations 1 (800-1) executive software after the indication processing (24-2), the processing (24-3) of each base station that group of base stations 1 (800-1) comprises by obtaining new software, for example obtain new software, carry out software passed on to net management device (250) and finish the processing (24-4) of replying via circuit IF (118).Net management device (250) is carried out the processing (24-5) that business stops to move is forbidden in group of base stations 1 (800,1) base station (800-x) in addition, and group of base stations 1 (800-1) executive software is upgraded indication handle (24-6).In addition, above-mentioned processing (24-5) also can be omitted.
After the base station that group of base stations 1 (800-1) comprises receives this indication, the software upgrading processing (24-8) of (24-7) and electric wave signal (frequency f 2) handling part is handled in the software upgrading of carrying out electric wave signal (frequency f 1) handling part successively, after the software upgrading processing (24-9) of device management portion (121) finished, net management device was carried out the processing (24-10) that the software upgrading end is replied.The detailed process such as the Figure 25 of (24-7,8) handled in the software upgrading of each electric wave signal handling part, the more detailed processing as shown in figure 26.In addition, detailed explanation is with aftermentioned.In addition, the software upgrading of device management portion (121) detailed process of handling (24-9) with shown in Figure 20 respectively handle identical.In addition, handling (24-7,8,9) can carry out with suitable order.For example, in the frequency that can select successively to be scheduled to one, (24-7,8) are handled in the software upgrading of the frequency of selecting.
Net management device (250) is carried out the processing (24-11) of the base station of reselecting (groupization) update software after accepting software upgrading and finish to reply from all base stations that group of base stations 1 (800-1) comprises.Below, the set of the base station of selection is called group of base stations 2 (800-2).Net management device 250 is carried out the processing (24-12) that this group of base stations 2 (800-2) request software is passed on.In addition, processing (24～12) is identical with above-mentioned processing (24-2).Net management device (250) is carried out and the processing that group of base stations 1 (800-1) is carried out (processing that 24-2～24-10) is same group of base stations 2 (800-2).Handle up to the base station disappearance which group of base stations does not belong to by carrying out these repeatedly, can carry out the software upgrading of all base stations.
In addition, in base station (for example, formation shown in Figure 22) that a plurality of frequencies can be communicated by letter and wireless communication networks that base station (for example, formation shown in Figure 2) that a frequency can be communicated by letter mixes, by as select the base station of update software above-mentionedly, but non-interrupting service ground carries out software upgrading.In addition, make group of base stations in the present embodiment, but also can not do in groups, to all base stations one by one frequency carry out software upgrading successively.This occasion, above-mentioned processing (24-1) can be omitted.
Figure 25 is the action flow chart that the detailed process of (24-7,8) is handled in the software upgrading of each electric wave signal handling part of explanation.At first device management portion (121) carries out the transmitted power minimizing request processing (25-1) of all sectors to electric wave signal (frequency f x:x is 1 or 2) handling part (123-x).Electric wave signal (frequency f x) handling part (123-x) reduces the processing (25-2) of the transmitted power of all sectors gradually.Thereby the calling that frequency f x covers switches to other frequencies, and the communication service of this calling continues.On the other hand, become the state that communication service does not provide among the frequency f x.Electric wave signal (frequency f x) handling part (123-x) is carried out the processing (25-3) of replying finishing to device management portion (121) after the transmitted power that finishes all sectors reduces processing.
Device management portion (121) carry out to confirm that calling that all sectors of electric wave signal (frequency f x) handling part (123) connect is after zero the processing (25-4), to carry out the processing (25-5) to the software upgrading of electric wave signal (frequency f x) handling part (123-x) request electric wave signal (frequency f x) handling part (123-x).After electric wave signal (frequency f x) handling part (123-x) was accepted the software upgrading request, by the reset processing (25-6) of carrying out self, that carries out new software read in processing (25-7).Here, the software that reads in for example can be used as the software of obtaining in the processing (24-3).Then, the reopening that electric wave signal (frequency f x) handling part (123-x) is carried out electric wave signal (frequency f x) handling part (123-x) is handled (25-8) and is improved the processing (25-9) of the transmitted power of all sectors that electric wave signal (frequency f x) handling part (123-x) comprised gradually, thereby the communication process of all sectors of frequency f 1 becomes possibility once more.
When the processing (25-9) that improves the transmitted power of all sectors that electric wave signal (frequency f x) handling part (123-x) comprised gradually finished, electric wave signal (frequency f x) handling part (123-x) was carried out to device management portion (121) software upgrading is finished the processing (25-10) of replying.In addition, call out each sector that switches to other frequencies in order to make, the processing of Figure 25 can not carried out each electric wave signal handling part (123) simultaneously, carries out successively but handle shown in (24-7,8) according to the software upgrading of each electric wave signal handling part (123) of Figure 24.
Figure 26 is the action flow chart of the processing (25-2) that the transmitted power of all sectors shown in Figure 25 reduces gradually when describing frequency in detail and being f1.In addition, the occasion of frequency f 2 too.After accepting transmitted power and reduce request (25-1) from the CPU (111-4) of device management portion, the CPU (111-5) of the sector control part (120`-1) of electric wave signal (frequency f 1) handling part (123-1) begins to reduce the processing (26-1) of transmitted power.CPU (111-5) reduces amplitude in order to make transmitted power only reduce predetermined electric power, carries out to wireless IF (116-1～3) processing of request (26-2).
After wireless IF (116-1～3) accepts request, carry out the transmitted power minimizing and handle (26-3), and carry out processing (26-4) the transmission power value notice CPU (111-5) after the transmitted power minimizing.CPU (111-5) carries out whether the performance number of judging wireless IF (116-1～3) notice is the processing (26-5) of the lower limit of transmitted power, on the other hand, if not lower limit is then handled (26-2) once more.If the performance number of notice reaches lower limit, then carry out the end process (26-3) that transmitted power reduces.
By these processing, can reduce in the base station transmitted power of the frequency f x of all sectors in this base station gradually, to provide the communication path of communication service to switch to other frequencies in this base station, make the state that communication service is not provided among the frequency f x of all sectors in this base station, and the relevant module of renewal frequency fx is the software of electric wave signal (frequency f x) handling part.In addition, in the above-mentioned processing preceding sector is increased and reduces the transmitted power of frequency f x, still, also can increase minimizing successively each sector.

After the base station that group of base stations 1 (800-1) comprises receives this request, carry out the software upgrading of signal processing part (frequency f 1 usefulness) successively and handle (31-7), (31-8) handled in the software upgrading of signal processing part (frequency f 2 usefulness), (31-9) handled in the software upgrading of sectors electric wave signal handling part, the software upgrading of sector β electric wave signal handling part is handled the software upgrading of (31-10) and sector gammai electric wave signal handling part and is handled (31-11), after the software upgrading processing (31-12) of device management portion (121) finishes, carry out the processing (31-13) that the software upgrading end is replied to net management device.The software upgrading of (31-7～12) is an example in proper order in addition, also can be arbitrarily in proper order.For example, select a frequency successively from predetermined a plurality of frequencies, the pairing signal processing part of frequency to selecting can carry out software upgrading successively.In addition, can select successively too, can carry out software upgrading successively the pairing electric wave signal handling part of selecting in sector to each sector.
Each frequency is handled the detailed process such as the Figure 32 of (31-7,8) with the software upgrading of signal processing part (124-1,2), the more detailed processing as shown in figure 33.In addition, the detailed process of (31-9～11) is handled in the software upgrading of each sector electric wave signal handling part (125-1～3), as Figure 34, and more detailed the processing as shown in figure 35.In addition, the detailed process of the software upgrading of device management portion (121) processing (31-12) is identical with Figure 20.
After all base station receiving softwares that net management device (250) comprises from group of base stations 1 (800～1) upgrade and finish to reply, carry out the selection (groupization) of the base station of update software and handle (31-14).The selection of base station can be same with the method for Fig. 7～12 and explanation thereof.Below, the set of the base station of selection is called group of base stations 2 (800-2).250 pairs of these group of base stations 2 (800-2) of net management device are carried out the processing (31-15) that request software passes on.In addition, processing (31-15) is identical with above-mentioned processing (31-2).Net management device (250) is carried out and the processing that group of base stations 1 (800-1) is carried out (processing that 31-2～31-13) is same group of base stations 2 (800-2).By these are handled up to the base station disappearance which group of base stations does not belong to repeatedly, thereby, can be to the software upgrading of all base stations.In addition, the selection of group of base stations also can be omitted.
Figure 32 is the action flow chart that the detailed process of (31-7,8) is handled in the software upgrading of each signal processing part of explanation.At first, device management portion (121), the transmitted power of each sector electric wave signal handling part (125-1～3) being carried out the frequency f x of all sectors reduces request and handles (32-1).Each sector electric wave signal handling part (125-1～3) is carried out the processing (32-2) of the transmitted power of the frequency f x (f1 or f2) that reduces each sector gradually.Thereby, the regional narrow and small zone that covers to the frequency f 1 of base station BS 1 and 8 (110```-1 and 8) shown in Figure 29 that frequency f x covers, the calling that frequency f x covers switches to other frequencies (Figure 29 medium frequency f2), and the communication service of this calling continues.The sector electric wave signal handling part (125-1～3) of each sector is carried out the processing (32-3) of replying finishing respectively after finishing the transmitted power minimizing processing of frequency f x to device management portion (121).
Device management portion (121) carry out to confirm that calling that all sectors of frequency f x connect is after zero the processing (32-4), carries out to (124-x) processing (32-5) of request signal handling part (frequency f x with) software upgrading (124-x) of signal processing part (frequency f x with).
Signal processing part (frequency f x with) (124-x) accept the software upgrading request after, by carrying out self reset processing (32-6), that carries out new software reads in processing (32-7), after reopening processing (32-8) end, carry out signal processing part (frequency f x uses) to device management portion (121) and reopen end notification (32-9).Here, the software that reads in can be for example to handle the software that (31-3) obtains.Device management portion (121) from signal processing part (frequency f x with) (124-x) accept to reopen end notification (32-9) after, all sector transmitted powers that each sector electric wave signal handling part (125-1～3) is carried out frequency f x increase request and handle (32-10).The transmitted power that each sector electric wave signal handling part (125) is accepted frequency f x increases request, carries out the processing (32-11) that improves transmitted power gradually.(for example, thereby the communication process of all sectors f1) becomes possibility to frequency f x once more.
When the processing that transmitted power improves gradually (32-11) finished, each sector electric wave signal handling part (125-1～3) is carried out device management portion (121) increased the processing (32-12) that end is replied to frequency f x transmitted power.In addition, because the calling of the processing of Figure 32 switches to each sector of other frequencies, thereby each signal processing part (124) is not carried out simultaneously, for example (31-7 is handled in the software upgrading of each signal processing part (124) of Figure 31,8) shown in, carry out successively to frequency one by one.For example, among the processing 31-7 of Figure 31, make fx=f1 carry out each processing of Figure 32, among the processing 31-8 of Figure 31, make fx=f2 carry out respectively handling of Figure 32.
Figure 33 is the action flow chart that describes the processing (32-2) that the transmitted power of frequency f x shown in Figure 32 descends gradually in detail.In addition, though Figure 33 has illustrated sectors, the situation of sector β and sector gammai is also identical.After the transmitted power of having accepted frequency f x from the CPU (111-4) of device management portion reduced request (32-1), the CPU (111-11) of sectors electric wave signal handling part (125-1) began to reduce the processing (33-1) of the transmitted power of frequency f x.CPU (111-11) asks wireless IF (116-1) to make the transmitted power of frequency f x reduce the processing (33-2) that predetermined electric power reduces amplitude.Wireless IF (116-1) accepts this request, carries out the transmitted power minimizing and handles (33-3), and carry out the processing (33-4) with the transmission power value notice CPU (111-11) after the transmitted power minimizing.
CPU (111-11) carries out whether the performance number of judging wireless IF (116-1) notice is the processing (33-5) of the lower limit of transmitted power, if not lower limit is then handled (33-2) once more.On the other hand, the performance number of notice is then carried out the end process (32-3) that transmitted power reduces if reach lower limit.For example, CPU (111-11) is to the CPU of device management portion (111-4), and frequency of notification fx transmitted power reduces processing and finishes to reply.
By these processing, the base station can reduce the transmitted power of the frequency f x of all sectors in this base station gradually, to in this base station, provide the communication path of communication service to switch to other frequencies, make the state that communication service is not provided among the frequency f x of all sectors in this base station, and the relevant module of renewal frequency fx, the i.e. software of signal processing part (frequency f x uses).
Figure 34 is the action flow chart that the detailed process of (31-9) is handled in the software upgrading of explanation sectors electric wave signal handling part.In addition, the processing (31-10,31-11) when sector β and sector gammai is also identical.At first device management portion (121) carries out the transmitted power minimizing request processing (34-1) of whole frequencies to sectors electric wave signal handling part (125-1).The processing (34-2) that sectors electric wave signal handling part (125-1) execution reduces the transmitted power of whole frequencies of sectors gradually.Thereby, the regional narrow and small zone that covers to the sectors of illustrated base station BS 1 of Figure 30 and 8 (110```-1 and 8) that whole frequencies of sectors cover, the calling that whole frequencies of sectors cover switches to other sectors (the β sector of base station BS 3 (110```-3) in the terminal MS 2 (300-2) of Figure 30), and the communication service of this calling continues.After the transmitted power of whole frequencies of sectors electric wave signal handling part (125-1) end sectors reduces processing, carry out the processing (34-3) of replying to device management portion (121) to finishing.
Device management portion (121) carry out to confirm that calling that the sectors of whole frequencies connects is that request sectors electric wave signal handling part (125-1) carries out the processing (34-5) of the software upgrading of sectors electric wave signal handling part (125-1) after zero the processing (34-4).After sectors electric wave signal handling part (125-1) is accepted the software upgrading request, by carrying out self reset processing (34-6), that carries out new software reads in processing (34-7), reopen handle (34-8) and finish after, carry out the processing (34-9) of the transmitted power that improves whole frequencies gradually.Here, the software that reads in is for example to handle the software that (31-3) obtains.Thereby the communication process of whole frequencies of sectors becomes possibility once more.
When improving processing (34-9) end of transmitted power gradually, sectors electric wave signal handling part (125-1) is carried out the processing (34-10) that sectors electric wave signal handling part software upgrading end is replied to device management portion (121).In addition, switch to other sectors in order to make to call out, the processing of Figure 34 is not carried out simultaneously to each sector electric wave signal handling part (125), for example, can handle shown in (319～11) according to the software upgrading of each sector electric wave signal handling part (125) of Figure 31 and carry out successively.
Figure 35 is the action flow chart that describes the processing (34-2) that the transmitted power of whole frequencies of sectors shown in Figure 34 reduces gradually in detail.In addition, Figure 35 has illustrated sectors, but the situation of sector β and sector gammai is also identical.After the transmitted power of accepting whole frequencies from the CPU (111-4) of device management portion reduced request (34-1), the CPU (111-11) of sectors electric wave signal handling part (125-1) began to reduce the processing (35-1) of the transmitted power of whole frequencies.
The wireless IF (116-1) that CPU (111-11) carries out this electric wave signal of request handling part carries out the processing (35-2) that makes transmitted power reduce predetermined electric power minimizing amplitude.Wireless IF (116-1) accepts this request, and the transmitted power of carrying out whole frequencies reduces handles (35-3), and carries out the processing (35-4) with the transmission power value notice CPU (111-11) after whole frequency transmitted powers minimizings.
CPU (111-11) carries out whether the performance number of judging wireless IF (116-11) notice is the processing (35-5) of the lower limit of transmitted power, if not lower limit is then handled (35-2) once more.On the other hand, if the performance number of notice reaches lower limit, then CPU (111-11) carries out the end process (34-3) that transmitted power reduces.For example, CPU (111-11) reduces the CPU that processing finishes answer notification device management portion (111-4) with whole frequency transmitted powers.
By these processing, the base station can reduce the transmitted power of whole frequencies of certain sector in this base station gradually, to provide the communication path of communication service to switch to other sectors or adjoining base station in this base station, make the state that communication service is not provided in the sector that meets in this base station, and can be to the relevant module in sector that meets, promptly the software of sector electric wave signal handling part upgrades.
